ELEMENTS OF GALVANIC BATTERIES.

SPECIFICATION forming part of Letters Patent No. 542,953, dated July 16,1895,

Application filed October 30,1894- Serial No. 527, (NO m l To aZZ whomit may concern.-

Be it known that we, FRANZ AUGUST VON ALIMONDA and Nine voN ALIMONDA,sub jects of the Emperor of Austria-Hungary, re-

siding at Gastello Alimonda, near Sagrado, in the district of Giiritzand Gradiska, in the Empire of Austria-Hungary, have invented certainnew and useful Improvements in the Elements of Galvanic Batteries; andwe do [0 hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention has relation to connections for the electrodes ofgalvanic and other batteries, and particularly for the carbonelectrodes; and it has for its object the provision of means whereby theleading-in wire may be readily secured to such electrodes, as will nowbe fully described, reference being had to the accompanying drawings, inwhich- Figure 1 is a perspective view of a portion of a carbon electrodeprovided with our improved connecting device. Figs. 2 to 7, inclusive,are sectional views illustrating various modes of securing theconnecting'wire to the electrode.

In the figures, K indicates the electrode, and M the leading-in wirebent at right angles at one end to form an anchor m. The wire M may beanchored to the carbon electrode in various ways, either by forming agroove gin a plate or block 13 and a recess or socket g in the carbonfor the reception of said wire and its bent end or anchor m, as shown inFig. 2, or this arrangement may be reversed, as shown in 0 Fig. 3,01both groove and recess or socket may be formed either in plate 13, Fig.4, or in electrode, Fig. 5, or said groove may be formed partly in theelectrode and partly in plate B, with the socket in one or the other, asdesired,

and as shown in Figs. 6 and '7. In either construction the wire M willbe held against vertical, lateral, and rotary displacement, as will bereadily understood.

The plate B should of course be of some material other than metal andmay be secured to the electrode in any desired manner-as by cementing orgluing, as by means of marine glue or other suitable adhesive.

In practice We preferably employ a carbon plate B and embed the wirebetween said plate and the electrode while the material is in a plasticcondition or during the molding of the electrode, said wire beingembedded between the electrode and retaining-plate during the casting ofthe same, the said plate forming an integral part of the electrode.

It will be seen that the mode of rigidly connecting the leading-in wireis a very simple and a very efficient one. The wire is held againstdisplacement in any direction, hence admits of a ready connection ordisconnection with a conductor when the latter is, for instance,provided with a plug and the lead ing in wire M with a plate m, Fig. 1,having formed therein a bearing for the reception of such plug. By meansof this arrangement a series of conductors-as, for instance, such asserve to connnect a series of elements of a galvanic or other battery toa line-wiremay be simultaneously connected or disconnected, 7 providedthe conductors are suiliciently rigid. On the other hand, the describedmode of connectin g the leading-in wire to the carbon electrodes admitsof the use of comparativelyshort wires,while the expensive binding-posts8c and the means for securing the same to the electrode are dispensedwith.

It will of course be understood that the described means forconnectingleading-in wires to electrodes is also applicable to metallic8 5 electrodes as, for instance, zinc electrodes; but

That we claim is- 1. The combination of a carbon electrode,

a retaining plate of the same material as and forming practically anintegral part of the electrode, and a leading in wire having its endbent at right angles to form an anchor, said wire anchored in thematerial between the electrode and retaining plate, for the pur- 5 poseset forth.

2. The combination with a carbon electrode provided with asemi-cylindrical groove g and a retaining plate of the same material asand forming practically an integral part of the mo electrode, said platehaving a corresponding groove and a recess 9 at thelower end thereof atright angles thereto, of a leading in wire having one end bent at rightangles, said wire seated in the aforesaid grooves with its bent endprojecting into the said recess, for the purpose set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
